Yo i had 2 audiobahn in a pre-fab bandpass(one note wonders) and thought they sounded good.But i was told if i build a box it would sound better,it was hard to believe. I built a 6.6cu/ft @37 box for my crown vic, YO it surpass my expectation.
Just wish i had made it a little smaller , so my speakers and port had more then 5in. to breathe from trunk gate.But when i open trunk alittle bit it sound even better so i must have some cancellation???? I cant imagine if i had better Quailty speakers what it would sound like. I have to much rattling tho, with dampen. And that Hifonic Brutus 1600rms i cant complain had it a year with no probelm i would buy it again. I need some earplugs.
